The finite element method is used to study the influence of porosity and pore shape on the elastic properties of model porous media. The Young's modulus of each model was found to be practically independent of the solid Poisson's ratio. The results are in good agreement with experimental data. We provide simple formulae that can be used to predict the elastic properties of porous media, and allow the accurate interpretation of empirical data in terms of pore shape and structure.
